You shouldn't need any food if you have obsidian and ss. Just bring 2 overload flasks, 2 renewal flasks, 2 sara brew flasks, and like 12 super restore flasks. Only pick up invuln crystals.
And by bomb tanking you mean loading a familiar with super brews and soups and just eating the entire fight while getting constant heals from any melee/rangers on your team. I'm also down to do Vorago as DPS/Base if I'm online.
Just moved back into school for my (hopefully) last year of college. I don't know whether to feel excited or scared yet that I'm almost at that point where I face the real world.
